Refactor Power Library for Vendor Agnostic Uncore APIs
summary
Refactors the DPDK power library into a thin core plus pluggable drivers model that lets per-vendor user-space drivers register with power library and be auto-detected at runtime, avoiding rebuilds when kernel frequency drivers change. Adds vendor-agnostic Uncore APIs (bus frequency, link‑width controls, advertised performance levels) and an AMD uncore driver, targets DPDK 24.11, and uses Meson flags to enable/disable drivers. Expected results: smaller binary, fewer dependencies, and the ability for applications to select or probe optimal uncore performance states.
